OP
what exactly is your budget? It would help to define that before any specific recommendations.
Also I have never heard your Rega DAC, but I did used to own the Rega Apollo CD player. Can you tell me if the sound of the DAC-R is similar to the Apollo? The Apollo was a reasonably detailed but rather laid back type of presentation. The Mytek and Benchmarks mentioned here will sound very different, much more analytical. Is that what you are missing with the Rega?
